My abiding memory of the Bath Festival of Blues and Progressive Music of 1970 (Letters, 3 October), to give it its full title, was Pink Floyd coming on stage in the early hours with a local women’s choir to perform Atom Heart Mother, not to mention Led Zeppelin headlining on the Sunday night. It was a amazing lineup and, as a Glasto regular gearing up for the ticket sale this Sunday, I am so glad that Michael Eavis was there with us at the Shepton Mallet showground that weekend 48 years ago.Stephen FashChobham, Surrey
